Type the Greek letter Omega in upper case Ω or lower case ω in Microsoft Word, Excel, PowerPoint, or Outlook.  Both in Office for Windows and Office for Mac. 

Omega (uppercase Ω / lowercase ω) is the twenty fourth and final letter of the Greek alphabet. It is used to often denote the last or ultimate limit of a mathematical set theory.

Star Trek fans know the Omega molecule is announced by a large Ω on starship LCARS displays. </nerd>.

How Omega upper and lower case look in different fonts 

Here’s some examples of how the Omega upper case and Omega lowercase symbols look in common Office fonts in Word 365. 

Omega upper and lowercase symbol codes 

These are the important code numbers or values you’ll need to enter the two symbols.

Use the Alt + X shortcut in Word for Windows, for example type 03A9 then Alt + X to enter Ω.   

Or enter the value into Character Code fields in Symbol dialog boxes to jump to that symbol. 

Omega uppercase symbol Ω    U+03A9  
Omega lowercase symbol ω    U+03C9 

Quick access for commonly used symbols. 

If you use a symbol often, a fast way to enter it is AutoCorrect. 

Once in a document you can copy it to AutoCorrect and make your own shortcut. 

Word, Excel, PowerPoint and Outlook 

Insert | Symbols | Symbol and look for the Omega symbol using Character Code 03A9 or 03C9. 

Window 10 Emoji Panel

The Windows 10 Emoji Panel has the Omega symbol Ω.  Use Win + . (period/fullstop) to open the panel.

Choose the Symbols tab (the third of the top row icons), then the Language Symbols section which is marked by the capital Ω … handy that.  To find the Omega letters, scroll down the list.

Windows Character Map 

Similarly, the Windows Character Map accessory in all Windows releases. Character Map has a search feature, something missing from the Insert | Symbol in Office. 

Or use one of the hex character codes to jump to the right part of the list. 

MacOS and Office for Mac inserting characters 

On a Mac, to enter the Male, Female or combo symbol: 

  • Command + Control + Spacebar shortcut to open the Character Viewer.    
  • Search for “Omega“ should find the symbol you need. 

Despite the name Character Viewer, the Apple system tool will also insert characters into any program, including Office for Mac.
